I decided I wanted to try doing one of the proposed Delta wing configurations for the X-15-3 plane, I chose the one normally modeled with the diamond wingtips...I made it simply by taking my X-15 plans, stretching the fuse the scale amount(about 10 inches) and changing the top view to a delta with wingtips. I added some 3mm covers on the sides of the fuse to sort of give it a look like the fairings had. It gives it a bit more body. It's all completed except for painting now, and the fairings added quite a bit of stiffness to the body. It came out at 55.5" long and about 21" wing span which is slightly oversized just for wing loading. Weight is right at 13 oz rtf, but without paint, so assume about an ounce more finished.

Update 12/21/12 Since the world didn't end yet, i had enough time to paint the Delta X-15 and do the markings. Came right out at exactly 14 oz rtf. Pictures show it next to the X-15-2

Update 12/27 Good maiden this morning. CG and throws were spot on as was glide trim, very nice!
Here is the cg calculator I used:
